APPARATUS FOR CARBONATING AND DISPENSING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 652,810, dated July 3, 1900. Application filed Tune 3,1898. Serial No- 682,518. (No model.)

To all whom, it may concern:

Be it known that I, HARRY RoBnR'rsoN, a citizen of the United States, residing in the borough of Brooklyn,city of New York,county of Kings, and State of New York, have invented certain new and useful Improvements in Apparatus for Oarbonating and Dispensing Liquids, of which the following is a specification.

My invention relates particularly to devices for impregnating liquids to be used as beverages with carbonic-acid gas or other gas and for dispensing the saidliquids into glasses, bottles, or other receptacles after the process of carbonation has been completed; and its objects are, among-others, to provide a device of this character which will readily and thoroughly carbonate liquid without the necessity of making any connections between the different vessels and pipes in which the liquid and gas are contained or supplied or the use of a force-pump or other means for forcing the liquid into the carbonating-chamber against the pressure of gas therein when the pressure of the gas-supply in the said carbonating-chamber is equal to or somewhat in excess of the water-pressure; and to this end it consists of the combination of partsand arrangement of details hereinafter described and claimed, and illustrated in the accompanying drawing, which is a general perspective view of an apparatus for carbonating and dispensing liquids embodying myinvention, with the mixing or carbonating vessels shown in vertical cross-section.

The gas-supply tank A is provided with a valve A, controlling its outlet and communication with the pressure-regulator A and pressure-gage A located adjacent thereto on the pipe 13. This pipe 13 leads from the gas-- tank A to the mixing-chambers EE through the branch pipes B and has a valve B located thereon intermediate the said pressure-gage and the mixing-chamber. This valve is provided with a lever H, by which it is operated and is normally in an open position. The water-supply pipe 0 is provided with a valve 0, a pressure-regulator O and a gage O and communicates with the chamber E through the check-valve D and the auxiliary chamber E in the head of the said mixing-chamber.

These mixing chambers or tanks E and E are preferably located in tubs G, adapted to contain ice for the purpose of refrigerating the liquid in the said tanks, and thus causing it to more readily absorb the gas. The tanks, however, may be provided with other means, such as agitators or sprayers, to accelerate the absorption of gas. The mixing-tanks are con- ,nected by means of the pipe E which extends downwardly to the bottom of the tank E and communicates with the tank E at the head thereof. The tank E is provided with an outlet-pipe F, extending from the bottom of the same to the dispensing-valve F and faucet F This valve is provided with a spring h at the upper end of the rod and abutting against the head h of the same, which retains the valve normally in a closed position, with the ball on the lower end of said rod seated in the opening at the head of the tank, through which the pipe F communicates with the faucet; The branch pipe 13 is provided with check-valves B which operate to prevent liquid or gas from rising into the gas-pipe B and also to prevent communication between the chambers E and E through the said pipe. The valve D on the water-supplypipe also operates to prevent the entrance of water or gas from the mixingtank into the said pipe.

- The operation of this device is as follows: When it is desired to carbonate a given quantityof liquid, the valve 0 on the supply-pipe Y O is first opened, allowing the liquid to pass into the pressure-regulating chamber, which has been previously adjusted to the desired pressure, andthen through the check-valve D into the mixing-chamber E, the atmospheric air in the said chamber displaced by the water being allowed to escape'throughthe snifting-cock 0, one of which is located for that purpose at the upper part of each of the mixmeans which may be provided for the purpose of assisting absorption. hen the water has become thoroughly charged with the gas and it is desired to draw a quantity of the same,the lever II of the valve B is then pressed downwardly, first closing the said valve, and then coming in contact with the head of the dispensing-valve rod it will open the valve F and allow first any air which may be in the lower part of the chamber E to escape therethrough, and then the liquid, which will flow into the chamber E as soon as the pressure therein is reduced. The pressure of gas in the mixing-chambers being reduced by drawing the liquid, the water or other liquid from the supply-pipe C will flow into the tank E of its own force as soon as the pressure in said chambers becomes less than the waterpressure, taking the place of the liquid which is drawn and also supplying sufficient pressure to force the liquid in the chamber E through the dispensing-valve. The operation of drawing liquid may then be repeated as often as desired by simply pressing the lever II downward, closing the gas-supply pipe, and opening the dispensing-valve, the liquid from the supply-pipe C flowing in automatically and taking the place of the liquid displaced by each draft.

I have shown two carbonating-tanks, this being my preferred method of construction, as any given amount of liquid may be more readily carbonated by the use of two mixingchambers than by one, because a greater surface of liquid is in this manner exposed to the gas; but it is obvious that the device would operate as well with one mixing-chamber and a proportionately-small amount of liquid to be carbonated and dispensed.

Vhat I claim is- 1. In an apparatus for carbonating and dispensing liquids, the combination of a gassupply under pressure and a liquid-supply through Valves, a mixing-chamber to which said gas and liquid are supplied, a Valve for dispensing liquid from said mixing-chamber and a mechanism by the operation of which first the valve controlling the gas supply and pressure is closed and second the said dispensing valve opened; the valve through which the liquid is supplied adapted to be closed by the gas-pressure and opened by the liquid-pressure.

2. In an apparatus for carbonating and dispensing liquids the combination of a mixingchamber provided with a gas-supply under pressure and a liquid-supply through tubes having valves thereon and an outlet for the carbonated liquid; the valve on said liquidsupply tube admitting of influx into said mixing-chamber by the pressure of the liquid, and adapted to be closed by the gas-pressure, and means whereby the gas supply and pressure is shut off when the liquid-outlet is opened.

In witness whereof I have hereunto set my hand this 10th day of May, 1808.

HARRY ROBERTSON.
